Modern Systems Analysisand DesignFourth EditionJeffrey A. Hoffer Joey F. GeorgeJoseph S. Valacich Chapter 5 Initiating and Planning Systems Development Projects
Learning Objectives • Describe steps involved in project initiation and planning. • Explain the need for and contents of Statement of Work and Baseline Project Plan. • List and describe methods for assessing project feasibility. • Describe tangible vs. intangible costs and benefits, and one-time vs. recurring costs and benefits. • Perform cost-benefit analysis, and understand time value of money, present value, discount rate, return on investment, and break-even analysis. • Describe rules for evaluating technical risk of systems development projects. • Describe activities and roles of structured walkthroughs.
Project Initiation Tasks • Establish: • Initiation team • Relationship with customer • Project initiation plan • Management procedures • Project management environment • Project workbook
Project Planning Tasks • Describe project scope, alternatives, feasibility. • Divide project into tasks. • Estimate resource requirements and create resource plan. • Develop preliminary schedule. • Develop communication plan. • Determine standards and procedures. • Identify and assess risk. • Create preliminary budget. • Develop a statement of work. • Set baseline project plan.
Deliverables and Outcomes • Business Case • Justification for an information system, expressed as tangible and intangible costs and benefits, and technical/organizational feasibility • Baseline Project Plan (BPP) • Statement of Work (SOW)
Statement of Work (SOW) is a “contract” between the IS staff and the customer regarding deliverables and time estimates for a system development project.
System Service Request (SSR) is a form requesting development or maintenance of an information system. It includes the contact person, a problem statement, a service request statement, and liaison contact information.
Assessing Project Feasibility • Economic feasibility • Technical feasibility • Operational feasibility • Schedule feasibility • Legal and contractual feasibility • Political feasibility
Economic Feasibility • Cost-benefit analysis: identify all the financial benefits and costs associated with a project • Tangible vs. intangible benefits • Tangible vs. intangible costs • One-time vs. recurring costs
Tangible Benefits Benefits that can be measured in dollars and with certainty
Benefits that cannot easily be measured in dollars or with certainty
Types of Costs • Tangible: can be measured in dollars and with certainty • Intangible: cannot easily be measured in dollars or with certainty • One-time: a cost associated with project start-up and development or systems start-up • Recurring: a cost associated with ongoing evolution and use of a system
Possible IS Project Costs • Procurement • Consulting, equipment, site preparation, capital, management time • Start-up • Operating systems, communications installation, personnel hiring • Project-related • Application software, software modification, personnel, overhead, training, data analysis, documentation • Operating • System maintenance, rental, asset depreciation, operation and planning
Three Financial Measurements for Economic Feasibility • Net Present Value (NPV) • Use discount rate to determine present value of cash outlays and receipts • Return on Investment (ROI) • Ratio of cash receipts to cash outlays • Break-Even Analysis (BEA) • Amount of time required for cumulative cash flow to equal initial and ongoing investment
Definitions of Terms • Present value: current value of a future cash flow • Discount rate: rate of return used to calculate the present value of future cash flows • Time value of money (TVM): comparing present cash outlays to future expected returns
Net Present Value PVn = present value of Ydollars n years from now based on a discount rate of i. NPV = sum of PVs across years. Calculates time value of money.
Technical Feasibility • Assessing the organization’s ability to construct the proposed system • Takes into account various project risk factors
Project Risk Factors • Project size • Team size, organizational departments, project duration, programming effort • Project structure • New vs. renovated system, resulting organizational changes, management commitment, user perceptions, amount of user information in system development effort • Development group • Familiarity with platform, software, development method, application area, development of similar systems • User group • Familiarity with IS development process, application area, use of similar systems
High technical familiarity mitigates risk due to project size and structure. Low familiarity increases risk.
Other Feasibility Concerns • Operational • Does the proposed system solve problems or take advantage of opportunities? • Schedule • Can the project time frame and completion dates meet organizational deadlines? • Legal and Contractual • What are legal and contractual ramifications of the proposed system development project? • Political • How do key stakeholders view the proposed system?
Building and reviewing BPP Baseline Project Plan (BPP) is a document intended primarily to guide the development team. Sections: • Introduction • System description • Feasibility assessment • Management issues
Project Scope statement is part of the BPP introduction. Sections: • Problem statement • Project objectives • Project description • Business benefits • Deliverables • Expected duration
Factors in Determining Scope • Organizational units affected by new system • Current systems that will interact with or change because of new system • People who are affected by new system • Range of potential system capabilities
Diagram Depiction of Project Scope Context level is a top level data flow diagram. Data flow diagrams are covered in Chapter 7.
Structured Walkthroughs • A peer-group review of any product created during the system development process • Roles: coordinator, presenter, user, secretary, standard-bearer, maintenance oracle • Can be applied to BPP, system specifications, logical and physical designs, program code, test procedures, manuals and documentation
Summary • In this chapter you learned how to: • Describe steps involved in project initiation and planning. • Explain the need for and contents of Statement of Work and Baseline Project Plan. • List and describe methods for assessing project feasibility. • Describe tangible vs. intangible costs and benefits, and one-time vs. recurring costs and benefits. • Perform cost-benefit analysis, and understand time value of money, present value, discount rate, return on investment, and break-even analysis. • Describe rules for evaluating technical risk of systems development projects. • Describe activities and roles of structured walkthroughs.
